Rooting Home Assistant through MeshCore: XSS attacks with a LoRa node name | Sasha Romijn (mxsasha.eu)

A crafted MeshCore node name could compromise any Home Assistant instance running meshcore-card as soon as someone viewed a dashboard with that card.

The same XSS (cross-site scripting) pattern appears to be present in MeshCore-Home-Assistant-Panel-v2 and its HACS variant

To be abundantly clear, and the post goes into detail why, this is not a bug in MeshCore but rather in how web dashboards are not properly sanitizing untrusted input. In this case, the untrusted input is via a field that any malicious MeshCore node could send.

Well worth a read and a follow on their Mastodon.
